American Capital Enterprises, Inc. Debt Collection Complaint

American Capital Enterprises, Inc. Debt collection department,

I do not know Cont'd attempts collect debt not owed Debt is not mine California

An item on my credit report says I owe a debt that I did not know about. As I have not had any loans or credit cards since around 2004, If this is my debt, it is over the 7 year reporting limit, and it is also a time barred debt ( Cal. Civ. Proc. Code 312 et seq. ), so it should not still be reporting on my credit report. I have disputed this item on my credit report and been told it will not be removed, but requests for proof that is my debt and when this debt was last paid, have gone unanswered.
